1996 Isuzu Trooper Crankshaft bolt is impossible to turn

depend on motor size but any hardcast bolt with lockn nut should work... ace hardware or lowes has a isle of harded cast bolts and nuts

counter clockwise with an impact wrench

Sometimes you have to heat the head of the bolt with a torch the use an impact wrench to break it loose.

If you don't have access to the above, you can remove the starter motor and jam the flywheel with a screwdriver or something and use a long breaker bar on the crankshaft bolt. (Kind-of the hard way, but it can work)

If you are replacing the water pump, it is recommended that you also replace the timing belt and the belt tensioner pulley while you are in there. I also personally recommend replacing the camshaft, crankshaft, and oil pump shaft seals. This can keep you from having to go back in there because of an oil leak. If this is all done at the same time, there will be no need to go back in there for another 60,000 miles.

Timing belt installation

1. Ensure locking bolts located correctly [4] & [5] in the picture below:


CS = Crankshaft
CA = Camshaft
IP = Injection Pump

2. Ensure timing marks aligned [10].
3. Fit timing belt in clockwise direction, starting at crankshaft sprocket.

NOTE: "ISUZU" lettering on belt should be readable from front of engine.

4. Slacken tensioner pulley bolt [9]. Push tensioner pulley against belt.
5. Ensure belt is taut between injection pump sprocket and tensioner pulley as well as crankshaft sprocket and camshaft sprocket.
6. Position tensioner lever [8] against tensioner pulley housing.
7. Remove locking bolts from sprockets [4] & [5].
8. Apply a load of 10 ... 12 kg to tensioner lever. Use spring balance [11].
9. Tighten tensioner pulley bolt to 80 Nm.
10. Turn crankshaft slowly 45 degrees anti-clockwise. Use spring balance to tension belt.
11. Repeat tensioning procedure at 45 degrees intervals for one anti-clockwise turn of the crankshaft.

NOTE: DO NOT turn crankshaft clockwise during tensioning procedure!

12. Fit tensioner lever to original position. Tighten nuts [12].
13. Install: Injection Pump flange [6], Camshaft sprocket flange [7], and water pump pulley.
14. Install components in reverse order of removal & refill coolant.

STEPS TO REMOVE HEATER CORE IN 1996 ISUZU TROOPER

1. Remove battery cables.
2. You have to remove the upper dash pad on this paticular year model. with a 10 mm socket and a 1/2 inch extension remove the 5 retaining bolts. Remove the blower assembly under the passenger side of dash.
3. Remove passenger side seat and center counsole.
4. Drain radiator.
5. Disconnect hoses from now exposed heater core.
6. Turn it 180 degrees and slide out.
7. Replace in reverse order.

you turned it the right way but will have to use an air impact to get it loose or a hammer to hit the ratchet or breaker bar with, you need a half inch drive breaker bar to get it loose and it will have to be in gear and the emergency brake on to get it loose.

with fan and fan shroud removed use socket and long breaker bar (can use pipe on over breaker bar for extra length) put on and jam bar onto right side of vehicle chassis rail (your left when looking at engine) quickly flick ignition key to crank so it jolts crank bolt loose

Yep, your fly-wheel broke. what do you need to know?

You will Probably need a New Belt Tensioner. Draw a Diagram of the Belt Routing Before Removal of the Belt.You will need to Locate the Belt Tensioner. It has a Large Pulley on a Bracket that Has a Bolt in the Middle and a Smaller Pulley that Goes Under the Belt and Holds Tension on it. You will need to get a Wratchet, Socket, and Cheater Bar. Turn the Bolt On the Top Large Pulley with the Wratchet and Cheater Bar. This will Lower the Smaller Pulley So that you will be Able to Remove the Belt. Please Rate My Response! Thanks!

It loosens counter clockwise (normal thread), but it takes about 450lbs to loosen, then use the proper puller to pull that pulley or risk ruining the crankshaft. 1 note 450 LBS is a hi qyuality (like snap-on or mac tools) half inch ratchet with a large cheater pipe on it
